A 3He-4He dilution refrigerator with a lowest temperature of 1.90 +\_\_ 0.05 mK and a maximum circulation rate of 10 mmol s -I has been constructed. The apparatus is at present used for the study of 3He in high magnetic fields and as a precooling stage for nuclear demagnetization. The design and con
## Abstract A stimulatedβechoβbased technique was developed to measure the regional apparent diffusion coefficient (ADC) of hyperpolarized ^3^He during a single breathhold for diffusion times of 25 ms or greater. Compared to previous methods, a substantially shorter minimum diffusion time was achie
